T 0 all whom it may concern:

Be it known that I, LAWRENCE P. LEox- ARI), a citizen of the United States, residing at St. ('loud, in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Fresh-Air- Treatment 1 paratuses, of which the following is a speci 'cation.

My invention relates to devices for treating diseased lungs, throat or other respiratory organs with fresh or medicinally impregnated air and-has for its' object the provision of an improved apparatus for thispurpose that permits the patient remaining 2 within the house while breathing the outside air conveyed to him tl'lI'OLlgh a duct.

Heretofore in treating tuberculosis by the fresh air method of treatment it has been customary tohave the patient spend his time out-of-doors or if indoors by an open window during the day and at night slee with his head in an open cabinet out-o doors while his body remains indoors. These methods have been found objection able for obvious reasons and especially in the case of invalids confined to their beds and my invention consists in the rovision of a device by which during the ay the outside air is conveyed directly to the-nostrils of the patient through a duct while lying in bed or sitting in a chair, so that he can see and hear what is going on around him and converse and take nourishment and medicine without disturbing the a paratus. At night another device is empl tients head is inclosed in a flexible casing secured to the duct so as to insure breathing the outside air while asleep. V

The construction and operation of my imroved device will be explained in detail hereinafter and illustrated in the accompanying drawings in which Figure 1 is a view of the apparatus employed for treament during the day, Fig. 2, a view artly in section of the dill'user, Fig. 3, a side view of the inhaler, Fig. 4, a bottom plan view, and Fig. 5, a view of the diil'user used for night treatment.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

M y improved apparatus is-secured to the window A of the room where the patient is window so that one end is open to the outer oyed by which the pa- Z air and iscovered by a wire gauze screen 2. The duct- 1' may be of any length desired though for the most successful operation should not extend too far from window A, the length of the duct being regulated by lengths of pipe telescoping into each other and has preferably one or more right angle joints 3 so as to prevent a direct draft on the patient. t

The inner end of the ducts extends downwardl y as shown at 4 and has secured thereto a bag 5 which has its upper end held distended by means of s )rings 6 to form a chamher 7 for diffusing the air entering through duct 1 and allow it to become impregnated with the odor from the finely divided resinous material 8 contained in a compartment 9 around the end of said duct 1.

The bag 5 converges downwardly and has its lower end securedto a casing 10 shaped as shown in Figs. 3 and 4 to snugly fit the patients face around the nose, having the flat portion 1] to fit over the upper lip and the curved portion 12 to pass over the bridge of the nose.

13 indicates straps 01' strings for securing the inhaler in place, 14 indicating a flexible plate of fibrous material secured to strings 13 to engage the back of the patients head.

15 indicates a door in the Hat side 11 to permit the patient to reach the nose with a handkerchief when necessary without removing theinhaler from its position.

i 16 indicates an awning of ordinary construction on the outside of window A to protect the outer end of duct 1 from the weather and 17 a compartment to hold resinous material the odor of which commingles with the air passing into the duct.

For treatment at night I provide a bag 18 which is substituted for bag 5 and is formed to inclose the patients head with a band 19 to be secured around the neck and an opening 20, closed by buttons 21 springs, etc., to admit of the insertion of a hand to use a handkerchief and to removesputa without i removing the casing or bag.

When in use the exhaled air being warmer than the outside air it flows upwardly through the diffusing chamber 7, the downthrough duct 1, passing along through its upper portion to the outer air, the fresh out- 1 portion of duct 1.

wardly extending end of duct 1, and then out side air .passing inwardly along the lower I cl aim is 1.. In a fresh. air treatment apparatus, a duct opening to' the outside air, a diffusing chamber secured-tothe inner end of the duct, a compartment on the end of the duct within the diffusing chamber containing resinous material, and means to connect said diffusing chamber with the patients head, substantially as shown and described.

2. In a fresh air treatment apparatus, a duct opening to the outside air, a diil'using chamberfseeured to the inner end of the duct, afi'inhaler at the lower end of the diffusing chamber, shaped to surround the nose of the patient, a closed opening in said inhaler for inserting the hand, and means to secure the inhaler in position, substantially as shown and described.

3. In a fresh air treatment apparatus,

duct opening to the outside air, a diffusing chamber secured to the inner end of the duct, a compartment at the end of the duct and within' the diffusing chamber containing resinous material, an inhaler at the lower end of the diffusing chamber shaped to surround the nose of the patient, and means to secure the inhaler in position, substantially as shown and described.

4. In a fresh air treatment apparatus, a

duct opening to the outside air, a diffusing chamber secured to the inner end of-the duct, a compartment at the end of the duct and within the diffusing chamber containing I 5. A fresh air treatment apparatus corn- 'prisinga duct extending to the outei air, a screen over the exposedend of the duct, a box belowsaid exposed end containing resinous material, an awning covering said ex posed end and box, a flexible chamber on the inner end of the duct, a compartment on the inner end of the duct inside of said chamber containing resinous material, an inhaler at the lower end of said chamber shaped to surround the patients nose, said inhaler being provided with an opening in its side closed by a door for inserting the hand, and straps secured to said inhaler to secure it to the patients head, substantially as shown and described.

In testimony whereof I hereto afiix my signature in the presence of two witnesses. LAWRENCE P. LEONARD.
